What are we doing in Math?
We will resume our Math Flexible Groups this week.
We will continue working on Probability on Fridays:
SP3 - Describe the likelihood of a single outcome occurring using words, such as:
• impossible
• possible
• certain
SP4 - Compare the likelihood of two possible outcomes occurring using words, such as:
• less likely
• equally likely
• more likely
Our Basic Facts (multiplication and division) 1 minute practices and quizzes will continue to be administered throughout our flexible Math groups, with a quiz given on Fridays.
We will also continue working on N3 and N4 throughout the year.
Numbers - Mental Math (done all year):
N2 - Use estimation strategies, including:
• front-end rounding
• compensation
• compatible numbers in problem-solving contexts
N3 - Apply mental mathematics strategies and number properties, such as:
N4 - Apply mental mathematics strategies for multiplication, such as:

N2 - Use estimation strategies, including:

• compatible numbers in problem-solving contexts
N3 - Apply mental mathematics strategies and number properties, such as:
- skip counting from a known fact
- using doubling or halving
- using patterns in the 9's facts
- using repeated doubling or halving to determine answers for basic multiplication facts to 81 and related division facts
N4 - Apply mental mathematics strategies for multiplication, such as:
- annexing then adding zero (tacking on trailing zeros)
- multiply by 10, 100, 1 000
- multiplication of two single-digit numbers in powers of 10
- halving and doubling
- Tacking on trailing zeros (ex: 50 x 100 = 5000)
- Power of Ten (ex: 400 x 300 = 120 000)
- Doubling/Halving (ex: 25 x 14 = 350)
- 11's trick (ex: 62 x 11 = 682 Add the 6 and 2, then put the 8 in between)
(*67 x 11 =737 Add the 6 and the 7, then put the 3 from the 13 in the middle and regroup the 1 with the 6.
